The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of groundswell lining up for Lakey Pipe, and it’s shaping up to be a ripper of a fortnight for the experienced crew. The water’s sitting at a balmy 80°F – pretty much spot on average for this time of year, so no surprises there.
The pattern kicks off from Sunday the 6th of September, with a solid SSW groundswell already pushing in. We’re looking at waves around 6ft on the Sunday morning, with a long 14-second period and a light cross-offshore breeze from the SSE. The energy is already pumping hard with a reading of 1626, and it’s clean as a whistle. This is quality, powerful reef surf – not for the faint-hearted. By Sunday afternoon, the swell jumps to 7ft and the period stretches out to a very long 17 seconds, with the energy climbing to 2764. The wind stays cross-off, but it picks up a touch. Still, it’s clean and heavy.
Monday the 7th keeps the good times rolling. Morning and afternoon both see 7ft SSW swell at 14 seconds, with a gentle cross-off breeze. The energy is strong at 1770 to 1785. It’s consistent, clean, and powerful – excellent for those who know what they’re doing.
Tuesday the 8th starts with 6ft swell at 13 seconds, clean and cross-off, energy at 2288. But watch the afternoon – the swell drops to 5ft and the wind goes cross, not cross-off. The period jumps to a massive 18 seconds, and the energy spikes to 3094, but the wind chop and tide questions make it a bit more tricky. Still, that long period groundswell will be wrapping nicely around the reef.
Wednesday the 9th is a standout. The morning brings 8ft of SSW swell at 16 seconds, with a clean cross-off breeze. The energy is pumping at 3278. This is big, powerful, and beautiful – expert territory for sure. The afternoon backs off a touch to 8ft, but the wind shifts to cross, so the morning is the pick.
Thursday the 10th and Friday the 11th are steady. Thursday morning is clean with 6ft at 15 seconds, light cross-off. Friday morning is similar with 7ft at 16 seconds. Both mornings are excellent. Afternoons are a bit more marginal with tide and wind, but still surfable.
The weekend of the 12th and 13th sees the swell dip slightly to 5ft, but the quality remains high. Saturday the 12th is clean and cross-off all day. Sunday the 13th is a gem – 5ft in the morning but with a 19-second period, energy at 2419, and glassy conditions. The afternoon picks up to 6ft at 18 seconds, energy 2929. That’s a dreamy, long-period groundswell that will be pushing in clean lines.
The second week stays active. Monday the 14th has 7ft to 7ft swell, but the afternoon wind picks up to 12 mph. Tuesday the 15th is similar – clean mornings, breezier afternoons. The swell stays in the 6ft to 7ft range, with periods of 14 to 16 seconds.
Now, the real fireworks come in the final days. Saturday the 19th of September sees the swell jump to 7ft in the afternoon, with a 17-second period and light cross-off wind. Energy at 2846. Sunday the 20th is a true standout: 8ft SSW swell at 16 seconds, clean and cross-off, with energy readings of 3502 and 3376. Monday the 21st follows it up with another 8ft day, also at 16 seconds, with a light offshore breeze and energy hitting 3552. This is the best of the lot – big, powerful, and clean. Expert only, but absolutely firing.
Crowds at Lakey Pipe are often a factor, so expect company, especially on these peak days. But with this consistent, high-quality groundswell, the trade-off is worth it. If you’re experienced and ready for a proper reef slab, this is your window.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
